The way to smoke weed in London, Ontario. Made from a plastic bottle and ratchet piece melted into cap at top, you fill up a milk jug or XL cup with water and burn a pinky sized hole at the bottom corner of the bottle and insert that inside the water with the cap off. Now you are ready to pack your kush in the pisser cap you made with a metal ratchet piece and screw it firmly on the submerged bottle. All thats left is lighting your bowl and slowly lift up the bottle from the water to get that smoke in, unscrew the cap just after the last bit of water comes out the hole and put your mouth on it sucking smoke out while slowly pushing the bottle back in the water with your mouth and hand getting all the remaining smoke in the pisser. Duh LoNDoN WaY
Yo lets go smoke that pisser outside!
